Abstract

An experimental setup has been designed to example the effect of tilt-rotor blade stall flutter. The blade has to be designed so that it does not exceed the maximum permissible load on the rotor rig to be employed for wind tunnel tests, while maximising the blade loading to allow for the blade to be excited. Computational fluid dynamics (CFD) has been used to design a set of blades to meet the requirements of an experimental rotor rig. After completion of the blade design the placement of the strain gauges for the experimental blade was achieved through the use of a three dimensional structural model. The modes of the blade were examined to allow placement of the strain gauges in regions of large expected strains.
